Analysts say the U.S. and the entire world might have to take on a strategy reminiscent of the Cold War and contain North Korea, barring it's ability to share weapons or technology and communicating the reality of using nuclear weapons as a means of protecting South Korea.
At present, there isn't much the world is able to do to circumvent North Korea's intentions, Chaibong Hahm, a Rand Corp. specialist in California, said.
Despite international condemnation, there was an announcement by North Korea last weekend that it is beginning a program for development of 
Enriched Uranium. All of it would be weaponized.
The announcement, following its testing of a nuclear warhead last May, was the principal topic of discussion at the White House on Tuesday between President Obama and President Lee Myung-bak, of South Korea, who was visiting.
In a news conference given jointly, President Obama referred to North Korea's behavior as a grave concern and a threat and that his goal is finding a means of stripping weapons from North Korea.
We will seek denuclearization along the Korean peninsula strenuously, Obama stressed in the Rose Garden at the White House. President Lee Myung-bak stood with him.
President Obama said that North Korea's track record shows a proliferation making them unacceptable as another nuclear power.
Obama maintained that the U.S. and South Korea along with Russia, Japan and China, will never agree to North Korea's aspirations of being a nuclear power. He said that the historic paying off of North Korea not to develop nuclear weapons would end.
Obama says the U.S., along with other countries, have plans to restrict any North Korean ship that may be carrying weapons or weapons parts, as part of a United Nations declaration. Hahm said the Chinese altered the declaration, so ships may be stopped, but not boarded to be searched.
Obama said that concessions will no longer be made to North Korea but he still is willing to enter into negotiations.
Daniel Sneider, an expert regarding Korean issues residing at Stanford University, says there isn't much hope anymore that a quick agreement will be reached that will lead North Korea into giving up nuclear ambitions.
Sneider said that they need to consider this in terms of the Cold War. This is a case for containment and for deterrence.
Containment may come as a result of the exertion of financial pressure, stopping North Korea in its exports of nuclear technology to other nations considered "rogue nations," Iran in particular. Deterrence might come by threat of a nuclear attack from the U.S. as a response to nuclear strikes against any of our allies, including South Korea and Japan.
Lee left the rose garden with an assurance from Obama, who said the U.S. would continue to hold up a "nuclear umbrella" over the countries under threat. This gives South Korea a great peace of mind, said Lee.
